GAS STATION-METER.

SPECIFICATION forming part of Letters Patent No. 782,163, dated February'7', 1905.

Application filed June 13,1904. Serial No. 212,392.

To (LN It'll/(7711 it may concern:

Be it known that we, DONALD MCDONALD and Lvxx Mason SooFInLn, citizensof the United States, residing at Albany, in the county of Albany andState of New York, have invented new and useful Improvementsin GasStation-Meters, of which the following is a specification.

This invention relates to gas station-meters of the class commonly knownas wet meters, and has for its object to improve the construction of thesame to the end that the capacity of the meter may be very materiallyincreased and the revolving drum thereof rendered structurally strongerthan has heretofore been the case with meters of the class to which theinvention relates.

The meter herein shown is based upon the meter forming thesubject-matter of Letters Patent No. 62'38A5T. granted to (lharlcs \V.Hinman, December 5, 1899; and the invention aims to improve upon themeter disclosed in said patent primarily in providing additional bendsin the division-walls of the gas-pockets and in the manner of mountingthe drum upon the axle.

The purpose had in view in the novel features of construction embodiedin the present invention will be more clearly gathered from the detaileddescription to follow.

The invention is illustrated in the accompanying drawings, in whichFigure l is a central vertical longitudinal sectional view through anapparatus constructed according to our invention. Fig. 2 is a sectionalend elevation of the inlet end of the revolving drum. Fig. 3 isa centraltransverse sectional view of the drum. Fig. 4 is a sectional endelevation of the outlet end of the drum. Fig. 5 is a perspective view ofone of the partitions removed from the drum. Fig. (3 is a view of one ofthe end centers, and Fig. T is a view of the four-armed center.

Referring now to the drawings, 1 indicates the outer case, in which issupported upon an axle 2 a revolving drum 3. Said drum is provided atone end with a dry-well chamber 4, over which extends a hood 5, formingone end of the drum. Said hood is provided in its central portion with acircular bulge or enlargement 6, which is provided with a centralaperture 7.

8 indicates the dry well or inlet-pipe for the gas. which is supportedin the one end of the outer casing 1 and projects through the opening 7and upward within the dry-well chamber 4 to a distance above the normalwater-line indicated by the dotted line 9.

10 indicates the partitions or division-walls, which are arranged toform the gas-pockets of the drum, and each of these partitions has atthe inlet end of the drum an end wall ll, extending parallel to the endof the drum and triangular in shape. Extending outwardl) from the outerside of each end wall 11 is a wall 12, which is arranged to bear therelation ofa chord to the drum and which has an angular continuation 13extending to the circumference of the drum. The opposite end of the wall12 terminates short of the circumference in order to provide an outletfrom the dry-well chamber into the auxiliary compartment 14:. The outeredges of the walls 12 and of their continuations 13 abut against and maybe secured to the inner side of the hood 5, and said hood, together withthe walls 12 and 13 and the end walls 11 of the partition, form thedry-well chamber -L.

In the patent to Hinman above referred to his partition is provided withtwo bends, thereby forming a side wall with two wings extendingapproximately at right angles to each other. The portion of thedivision-wall or partition in the present case corresponding to the sidewall 1' of llinman is indicated by '15, the part corresponding to thesurface 2 is indicated by 16, and the part indicated by 3 by 17. It willbe seen from the drawings that an additional bend in the partition-wallis provided to afford at the end of the surface 16a wing or inclinedsurface 18, and at its opposite end the partition is correspoinlinglybent to provide adjacent to the surface 17 an additional wing orinclined surface 1%). Each of the partitions 10 is provided at theoutlet end of the drum with an end wall 20, substantially triangular inshape, and between each end wall 20 and the first plane or wing 19 ispro vided an offset 21, which is perpendicular to the plane of the endwall and extends from the apex of the end wall to the circumference ofthe cylinder. Correspondingly at the inlet end of the drum an offset 22is provided perpendicular to the end wall 11 and connecting said endwall with the first inclined surface or wing 18 of the partition. It maybe here stated that by forming these oifsets 21 and 22 at the respectiveends of the partitions we are enabled to impart to the first inclinedsurface or wing at each end of the partition a steeper slope, therebylessening the resistance to the water and insuring greater speed ofrotation. It will be seen that this relatively steep slope may beimparted to said first inclined surface or wing and at the same timeafford a constant area of discharge-port, thus giving a greatermeasuring-space to the compartment adjacent and insuring a smaller lossof measuring-space at the port-opening. In addition to these advantagesthe provision of this extra plane orinclined surface at each end of thepartition enables the drum to be braced from within in a manner togreatly strengthen the structure and render the parts of the drumcapable of withstanding the great strain to which they are subjected.The manner of mounting the drum and of bracing the partitions will nowbe described.

The axle 2 is mounted at opposite ends in bearings 23 and 24, thebearing 23 at the inlet end of the drum being provided with a support25, which extends well within the drywell chamber t to providesufiicient space for the entrance of the dry well 8. Said support 25 andthe support 26 for the bearing 24 are suitably mounted on the respectiveends of the outer casing 1. Near each end of the shaft 2 and keyed onsuch shaft is a rectangular cast-iron center 27 27, and bolted to therespective sides of each of these centers is a tangential arm 28, whichextend along the inner sides of the respective olfsets 21 22 of thepartitions to the circumference of the drum. The arms 28 are of coursebolted at suitable intervals to said offsets and at their outer ends arebolted to an encircling band 29 in the usual manner. By providing therectangular cast-iron centers 27 and securing the arms 28 thereto and tothe partitions in the manner described it will be seen that all shearingstress is removed from the bolts and that the strain thereon will bedirect. A series of braces 30 is also provided at each end of the drum,which radiate from each tangential arm 28 near its point of support tothe center 27 to the circumference of the drum and which are reinforcedby circular irons 31, concentric to the main construction.

32 indicates a main triangular truss spanning from end center to endcenter and having its apex at the periphery of the drum. The sides ofthis triangular truss extend along the sides of the side wall or surface15 of each partition, and its outer ends are connected by means of alongitudinal truss 33. Mounted on the axle 2, at the center thereof. isa castiron center 34 of four-arm form. Bolted to the apex of thetriangular truss 32 and extending along the surface of the side wall 15,to which it is also bolted, is a radial arm 35, the inner end of whichis secured to one of the arms of the center 3 1. It may be here statedthat there are four partitions in the drum shown, and consequently therewill be four radial arms 35, each one of which will be secured to one ofthe arms of the center at. The main truss 32 and the' radial arm 35 arereinforced by lattice-braces 36, as shown. The triangular truss 32 isfurther supplemented by a series of hip-trusses 37, which span from saidtruss to the triangular arm 28 and are connected together by means of ahipliner 38, bolted to the cast-iron center 27. The said cast-ironcenters 27 are concave on their outer faces, as indicated at 39, inorder to utilize all available space and at the same time properlyresolve all stresses. Flanges &0 project inward from the sides of eachof the end centers 27, which are utilized for attaching the longitudinalframe irons and truss-irons direct to the center instead of to thetangential arms 28.

From the foregoing, taken in connection with the drawings, it will beseen that the additional planes or surfaces provided at the ends of thepartitions permit placing of the face of the tangential armsperpendicular to the plane of the end walls, thus giving the maximumamount of strength and offering the greatest resistance to transversestress. Also said planes or surfaces permit of the attachment ofthehip-truss irons to the tangential arms in such manner as to avoid ashearing strain on the bolts. Furthermore, these additional surfacespermit a method of construction securing perfect riveting and solderingof the plates forming the dividing-partition at the junction of the hipslant and the end walls.
